B) "Someone is gifting free interesting content to the site". That's the attitude that caused Yahoo! Answers. SE has a higher quality bar, so that there are good, answerable questions. If a question seems unanswerable to many (not due to incompetence but due to incompleteness/clarity/broadness/etc), then it is put on hold. It can be reopened if it gets fixed; putting it on hold lets it get fixed, whilst preventing answers (which might use the wrong interpretation, etc) while it is getting fixed. Saves time for all.
